Fight against Arab Holocaust denial

Holocaust denial is flourishing in the Arab world. It's one of the 21st-century's fastest-growing forms of counterknowledge – but Western liberals are wary of drawing attention to it for fear of upsetting Muslims.

Meanwhile, the historian Robert Satloff is trying to "win over Arab hearts and minds" with his book Among the Righteous, which includes accounts of Muslims who saved the lives of Jews during the Second World War. They include Si Kaddour Benghabrit, rector of the Great Mosque of Paris, who saved up to 100 Jews by giving them certificates of Muslim identity.

We shall see how much impact these efforts make. I'm not optimistic – but anything is better than the dreadful example set by a few state schools in this country, which avoid teaching the subject for fear of provoking teenage Holocaust-deniers in the classroom.
